METHOD OF LAYING ROOFING MATERIAL.

manner.

Application filed. August 5, 1911.

To all Lt-7207771 itmay concern:

Be it known that I, Snnnwoon l3. FArsoN, a citizen of the United States,and'a resident of Cincinnati, Hamilton county, State of Ohio, haveinvented a certain new and useful Method of Laying Roofing Material; andI do declare the following to" be a clear, full, and exact descriptionof the invention, attention being called to the drawing whichaccompanies this application and forms a part thereof.

This invention relates to roofing and means for spacing and positioningroofing material while the same is being laid.

It is intended for use in connection with built-up roofing in whichtar-paper, tarfelt and similar prepared materials are employed. certainwidths, usually established standards. It is unrolled and laid instrips, generally lengthwise over the roof. These strips are laid toform superposed layers (plies), care being taken to break joint toprevent the joints in superposed layers to coincide with each other. Toavoid this a lap-joint is used between adjoining strips in adjoininglayers. A start 15 made at the cave of the roof, each sheet as laidlapping over the one laid previously below it.

In order to obtain a roof with a certain multiple of layers, a certainsystem is used in determining the space which the strips should lap or,what is the same, in determining how much higher up on'the roof eachstrip is to be laid. In doing this work it is essential that the stripsbe laid exactly parallel otherwise when the highest edge or ridge of theroof is reached, the edges of the roofing strips will be out ofparallelism. To obviate this, roofers help themselves in various ways asfor instance by using sticks notched out or cut to right length andwhereby the proper positioning of the edges of the strips is determined.This stick has to be used and is applied at each end of each strip.

The object of this invention is to provide means which take the place ofsuch sticks and other make-shift devices, which are more accurate and donot require as much time in their use, which may be used with moreconvenience and which, when used as intended, produce a roof of acertain multi-ply.

In the following specification and par- Specifioation of Letters Patent.

This material comes in rolls of Patented Feb. 5, 191 8.

Serial No. 642,482.

ticularly pointed out in the claim at the end thereof, will be found afull description of my invention, together with its manner of use, partsand construction, which latter is also illustrated in the accompanyingdrawing, in which i Figure 1, shows in perspective view a roof coveredwith tar-felt. Fig. 2, is an enlarged cross-section of a part of thisroof. Fig. 3, illustrates manner of use of my invention. Fig. a, showsat enlarged scale in perspective view a portion of the means used inconnection with my method.

A indicates the strips of prepared roofing material, like tar-felt,which comes in rolls and is applied as shown in Figs. 1, 2, and 3, upona base B consisting usually of board sheathing.

h The strips are laid as shown in Fig. 2, that is part of each striplaid is covered by the strip laid thereafter. The higher rear edges 5 ofeach strip are thus covered, leaving only the lower or front-edges 6exposed. The number of layers or plies desired determines how much ofthelower, previously laid strip, is to be covered by the strip to be laidnext, or what is the same, it determines how much higher up on the roofthe strip is to be laid above the previously laid strip. Thus forinstance in a three-ply roof, the front-edges of the strips are aboutone third of the width of the strips apart, that is a strip as laid islaid one third of the width of a strip back of the one previously laid,each strip being lapped fully two thirds of its width. In a four-plyroof the front edges of the sheets are about one fourth of the width ofa sheet apart. In many cases a measuring rule is used to measure offthis distance. Or this distance is transferred to a stick which isnotched out or cut down to length. Whatever is used has to be applied ateach end of each strip to establish the position of the strip. In placeof such means and devices I propose to use a tape 0 of a materialsuitable for the purpose, the same being provided with positioning marks0 spaced equal to the distance required between corresponding that is,upperlongitudinal edges of superposed strips in order to cause a stripto be laid, to lap over the previously laid strip so as to produce aroof of a certain ply. Thus, assuming the width of the strips to be 32inches, the distance on the tape between marks would be about ply roofthey would be about 7 inches apart. For use, one of these tapesis placedat each end of the roof with one end at the cave as shown in Fig. 3 andat right angles thereto, and if the roof is long, tapes may also beplaced between them. Suitable means, like nails may be used to preventdisplacement of the tapes while the roof is being laid.

It will now be understood that the laying of such a roof may beproceeded with with despatch and accuracy. The material. is simplyunrolled, cut-oil and each strip is positioned and laid as indicated bythe positioning marks. No time is lost by using a stickto measure oflfdistances each time for each end of each strip. No calculating has to bedone and since figuring is unnecessary, the possibility of makingmistakes is excluded, since there is only one mark or graduation foreach strip. I

The overlapping strips are secured to each other and to the roof-base byvarious means, usually nails and cement, but inasmuch as this procedureforms no part of my invention, a detailed description thereof isunnecessary, nor is it necessary to describe any preliminaryworkperformed on. the roofbase before the roofing is laid nor any workperformedto finish the roof. The tape being covered by the roofingmaterial, remains in position and becomes apart of the roof. For thesereasons it is proposed to make these tapes out of cheap paper ofsufiicient strength. Tapes with differently spaced positioning markswould be supplied to suit the several plies used which are mostly three,four and five ply. One tape could be used for at least two differentsets of marks, one

' on each side and more might be applied if different colors are used toindicate different marks. Inasmuch as this device is merely apositioning tape and not used for measuring sizes or distances, it isobvious that numerals which may only lead to confusion are not needed inconnection with the marks.

In tar-roofs made of tar-paper or tar-felt, tar or pitch is'generallyused as a cement. This material furnishes a suitable means to secure thetape in place by using it as a paste as indicated in Fig. a. It isdaubed on the roof-base to form stripes as shown at D in Fig. 4, uponwhich the tape is placed and whereby it is readily held in place untilthe roof is laid after which said tape becomes a permanentnndinseparable part ofthe roof, whereby it is entirely covered.

Havingdescribed my invention,I claim as new:

The method of laying roofing material which, in form of strips liketar-paper. or felt, is applied to the roof surface, parallel to theeaveof the roof and so that the strips at their longitudinal edges partlyoverlap each other, the extent of lap being governed thin material withun-numbered positioning marks so spaced that whenused for positioningthe strips, a roof of a certain pre determined ply results, of affixingstrips of said tape to the roof surface so as to extend parallel to eachother at right anglesfrom the cave of the roof and suitably spaced, oflaying the roofing material on top of these tapes so as to extend fromone tape to an other one, and ofpositioning the upper edge of each stripby means of the marks on said tapes to which it is alined.

In testimony whereof, I hereunto affix my signature in the presence oftwowitnesses.
